Today sucks. Second oil change, and when I went to put the drain plug back in it just spins. It will tighten up to a point, then loosen up again. Tried to pull it out and it just spins. My guess is that the pan is stripped out, or the thread insert is loose. How is it set up on an M60? Is there an insert in the pan, or is the pan tapped? Oddly enough though, I tightened it up as tight as it would go, and it doesn't seem to be leaking. Time for a new pan? Anybody parting an M60?
